Working Principle

The SMAJ11CA R3G TVS diode is a unidirectional device. This means that it only protects against voltages applied in one direction—positive (non-inverting) voltages. When a positive voltage is applied across the diode’s terminals, the diode begins to conduct current. This current is then dissipated as heat, protecting the device from voltage spikes.The diode’s design allows for fast recovery time and high surge capability. This makes it ideal for use in transient-sensitive circuit protection applications, as the diode can quickly respond to transient voltage spikes and clamp them to safe levels. The diode’s robust construction and high-performance characteristics make it suitable for a wide variety of applications.

Conclusion

The SMAJ11CA R3G TVS diode is a powerful and robust protection diode designed to protect semiconductors from electrical overstress caused by transient voltage spikes. It is designed for a wide variety of applications, including automotive electronics, computer systems, telecommunications systems, consumer electronics, medical electronics, power supplies, and more. Its fast response time and high surge capabilities make it perfect for transient-sensitive circuit protection applications.
